Here are some suggestions of what people have done to e each individually, or in combination. Let's not forget about the *Adaptive Learning* It all depends on driving style, driving conditions, etc. Symptoms vary from person to person, truck to truck. From what I've learned, from reading a gazillion posts about it over the years. I've had the 'chugggle' - 'hiccup' - 'stutter' since new. I am not looking to turn my truck into a 'hot rod' - I just want this hesitation and slow down to be corrected.Īny comments or recommendations are appreciated.
How does it affect the remaining emission warranty (since the basic warranty has expired).ĭoes this tuning work for this situation? Are there different types of tunes? I have read about "tuning" the EMC but really know nothing about this. I have taken it to the dealer 3-4 times to 'complain' and have them check it. These instances occur when going uphill and the speed decelerates then trying to accelerate when slowing down for a traffic light then accelerating when slowing down on a curve or turn and then accelerating - in all of these instances, there is a significant hesitation in which the truck slows even more. Since day one I have noticed a significant hesitation when transitioning from a slow speed and trying to then slowly accelerate. I own a 2016 Colorado with 3.6L engine and 6 spd transmission and have 46,000 miles (have had it for 39 most).
